Shepherd's pie is a classic British comfort food dish that is made with minced lamb or beef, vegetables, and topped with mashed potatoes. The meat and vegetables are cooked together in a rich gravy, then topped with a layer of creamy mashed potatoes. The pie is then baked until the top is golden and crispy. Shepherd's pie is a hearty and satisfying dish that is perfect for colder months. It is often served with peas or a side salad and is a favorite among both children and adults.
